There is nothing wrong with that from protocols point of view, and other clients such as cURL (for some protocols) and WebSockets apps use CONNECT to get through HTTP proxies as well. Dave, it looks like FileZilla did not receive FTP server Hello from Squid. I suggest that you take packet captures before and after Squid, to see whether Squid itself has received FTP server Hello from the FTP server. If Squid connected to the FTP server but received nothing, then the problem is on the FTP server side. Otherwise, the problem may be with Squid. HTH, Alex.
